` Be it known that` I, JOHN PULAUsKI, a

` citizen of the United States, residing at Cicero,in thefco'unty o f Cook and State of Illinois, have invented new and useful Imt provements in Airships, of which the fol- `lowing is 1a specification.

This invention relates to air-craft de'- and its object is to provide a novel and improved driving and controllin means, this objectv being attained by a com ination and arrangement of parts to `be' hereinafter de- 4.5l led scribed and claimed., i

"In order that the invention may be better understood, reference is had to the accompanying drawings forming a part of this specification, andin said drawings,

Figurevlvis an elevation of an air-ship constructedin accordance with the present invention; g

Fig. 2 is a medial cross-section of the same;`

Fig.j3 is a central' longitudinal section; Fig. 4'is-a perspectivevie'w of a rudder assembly;v

Fig. J5 is a, perspective'view of an elevatin plane;

' i 6 is'a detail in perspective showing the c osure of an observation tower and gun' house, and l y i Fig. 7 is-a perspectiveview showing an vengine support.

" Fig. 8- is an'elevation of the airshippshow` ingT-a modification; and

ig. 9. is a cross-sectionjof the same, taken 4onthe line 9'-9 of Fig. 8.

Referring specifically to the drawings, 10 denotes the body of ithecraft, the samebeing a metal shell, and havin a cylindrical tight compartment *11* adapted to be wlth vhydrogen or other'gas to. assist 1n sustaining the craft in the a1r.

Attlle forward end ofthe compartment 11 is located an engine 12 for drivin the main propeller12. The front end o this engine is pivoted, asshown at 13, to a base 13, the pivotalaxis. beingfhorzontal and extending transversely ofthe craft so .that the Aengine may be tilted, and as the propeller moves bodily with the engine, the p ropeller may be set et the proper mclmatlou for warfare, and

jwhen it is removed from t for ascending or descending. When going straight ahead, the engine will be set to bring the propeller axis horizontal.

' Any suitable mechanism may bc provided for'swinging the engine'12 for thepurpose stated. Fig. 3 shows a worm gearing 14 carried by the base 13, and operating a pinion 15 which is in mesh with a curved rack 15a on the engine.

vAn auxiliary propeller 16 is also located 0n each side of the craft near its forward end. Each of these ropellers is driven by an engine 16, Simllar propellers are 1ocated near therear end of the craft. The engines 16 stand out from the `sides of the -f craft to give the propellers 16 a free working area.

Aslshown in Fig. 7, each pair of engines 16 is slidably mounted on the branches 17 of a fork, the two forks being connected by a single shank 18 supported intermediate its ends in a bearing structure 19 suitably xed to-the bottom of the shell 10. The

shank 18 is adapted to be rocked to tilt the forks and thus tilt the engines so that their propellers may be set at an inclination in thesame manner and for the same purpose as the main propeller 12". This tilting of `the engines is effected bv a Worm wheel 20 on the shank 18 with which meshes a manually or otherwise actuated worm 2,0a supported by the bearing4 member 19.

If repairs are necessary, the engines 16* may be retracted or .drawn into the body 10 through suitably sealed openings 23 in the latter, this being done by non-traveling screws 21 threaded through the base castings of the engines and provided with handl wheels 22.

At thetop of the body 10 is an observa? tion and machine gun tower 24 having o enings 25 for aim in various directions. is tower has a normally closed top 26,/but as aiming at a high angle necessitates removal ofthe top, su porting guide rods 27, standf` ing outward m the tower, are provided,

`, onto which the top may be slid. Theto `26 has a` dependin annular Bange 28 whic seats with a tight t inside the tower. This iange is shaped to produce an encircling external groove in which the rods 27 .seat and' thus serve to hold the topA in place thereon e tower, as shown in Fig. 6. ,o I At the center of thebody 10 is held suspended a, basket 29 for supportmg machme' `rocked to set the' gun men, said basket being provided with a suitable lowering tackle 30, so that it may be lowered to relieve the' craft of the jar Vor concussion, andv also .to enable the machine gun men to have a clear view of the enemy craft.

The craftis also provided on each side with fore and aft elevating planes 31 'and 32, respectively. Each plane is carried by a medial rock shaft 32 entering the `shell 10 through a frame plate 33 mounted on the latter, and to the rock shaft is fixed a hand lever 35 for operating the same to tilt the plane at the desired angle. The frame plate 3-3 carries a toothed sector 34 engageable by a spring latch on the hand lever for locking the same. w

The front and 'rear edges of the plane have inwardly extending rods 36 passing through -arcuate slots 37 in the shell -10 and similar slots 38 in the frame plate 33. Each rod carries a pinion 39 which is in mesh with a curved rack 39a on the plate 33. AdjaCenttoeach pinion 39is a spring bolt 40 lwhich normally impedes movement of the pinion and locks the same against travel over the rack 39a. The bolt may be withv drawn by. a lever 41 carriedbythe lever 35 and acting on a pull Wire 42.` Thus, when the lever 35, with both levers 41, are gripped, a release-of the planev is at once effected, and the shaft 32a may, thenA be angle. l l

At the rear end 'of the body 10 are rudders 43 for changing the direction of' the craft laterally, the same being pivoted at 44 and having a connection 45 to swing together. Horizontal rudders 46 are also provided. Both sets of rudders are carried by rails 47 extending rearward from the body 10.

Entrance to thecompartment 11. is had through a rear door 48, and the compartment is provided with windows through sealed tubes 49. 1

The Wheels 50 for supporting! the craft on the ground are of conventionall design, and a detailed description thereof is not necessary;

In the modification of Figs. 8 and 9, the

plane at the vdesired use of a single enginelfb for each'pair of` propellers 16 -is shown.` The en e islocated centrally `of vthe airship`l dy, and power therefrom is transmitted to the propellers 16 through a shaft 5-1 and bevel' gears 52, supported 'by a suitable hanger 53. The. latter also has a downward 'extension '54, .whereby a pontoonV 55 may be 1'.,In an aerial craft, side propellers, e'ngines driving sai-d propellers, vand supports.
